Not receiving data for certain symbols.

Hi,
After updating to beta9 , the excisting intraday and non intraday charts for DX that I already have in certain workspaces do not load. Another words I get blank charts.
But I have no problem loading new charts of DX . What can I do to make sure I keep the DX charts I have in my workspace since I have done much work on them ( like trendlines , forks , etc...)?
Do I have to repair data? reset data?
Please let me know.

yellowTrader,

Perhaps you could check the dates on that chart and the session templates for it.

I have attached a picture of what it looks like.
I can't open the data series window to change the date or session templates.

Please attach your workspace file. Thanks.
